ABRAHAM EDWARDS, OF PHILADELPHIA, PENNSYLVANIAQ IMPROVE'M ENT INSEAL-JOlNTS FOR WATER-CLOSETS, 81,0.

Specification forming part of Letters Patent No. 222,578, dated December16, 1879; application filed September 24, 1879.

To all whom it may concern:

Be it known that I, ABRAHAM EDWARDS, of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Seal- Joints for Excluding Sewer and other Gasesand Smells from Water-Closets and other fixtures; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use it, reference being had to the accompanyingdrawings, which form part of this specification, in which Figure 1 is aside elevation of my invention. Figs. 2, 3, and 4: are vertical sectionsof the same, and Figs. 5 and 6 are detailplans.

My invention has for its object to provide means whereby sewer and othernoisome or offensive gases or efliuvia may be prevented from enteringdwelling-houses, stores, and apartments generally through the waste oroutlet pipes of wash stands or basins, bath and wash tubs, urinals,water-closets, or other fixtures through which water or other fluid ispermitted to flow, or wherein water is used for flooding or cleaningpurposes.

My invention consists, primarily, in the combination, with a sealcomposed of a movable cap or lid and a trough designed and adapted tocontain mercury, into which said lid (lips, of a sliding pipe which,when said "cap is raised, forms a close conduit between the pipe whereonsaid cap seats and the outlet of the fixture connected therewith, andwhich, when said cap is lowered, rests in said last-mentioned pipe belowsaid cap. The principal object of this sliding pipe is to prevent thelodgment of fecal, excrementitious, or other matter in or about themercury-trough or inside of the seal-cap when the latter is raised.

My invention consists, further, in the combination of certain parts,whereby, when the seal-cap is being raised, the sliding pipe will bedrawn up and brought into position to form the connection between theoutlet of the fixture, and when said cap is being lowered said slidingpipe will be moved down before and beneath it into the pipe on whichsaid cap rests.

My invention further consists in certain details of construction andcombination hereinafter set forth.

Referring to the accompanying drawings, A indicates a box or case, whichis designed to be connected in any suitable and appropriate manner withthe outlet of a wash stand or basin, bath or wash tub, urinal, orwater-closet, and to rest upon and be secured in any suitable manner toa waste-pipe, B, which conveys the discharge from such stand, basin,tub, urinal, or closet to a sewer, well, or other receptacle. In thedrawings 1 have shown the case formed with a flange, a, whereby it isbolted to a flange, c, of a water-closet basin, 0, and with anotherflange, a, whereby it is bolted to the pipe B, said basin projectingdownwardly into the case A and resting within a frame-work, D, providedwith a seat, 0?, and hinged cover D, and said pipe B being flange-boltedat b, or otherwise secured to a trap, E, of the usual or any suitableconstruction.

F represents a metallic cap or lid, having a depending flange or lip,'f,extending all the way around said lid to form an annulus or cordon, andadapted to enter a trough or channel, B, formed on the upper end of thepipe B, and designed to contain mercury, which latter is indicated at G.Said cap F is also formed with arms f f, hinged or fulcrumed at f f onpintles f f which have bearings on the flange b of the pipe B, and hasdepending cogged segments F F.

i H represents the sliding pipe, which normally rests in the pipe B,dipping into the trap E, and which, when raised, forms a close conduitbetween said pipe B and the outlet of the basin 0 or other fixture. Saidpipe H is formed with ribs h h, having openings or teeth h h, with whichthe cogs of the segments F F mesh.

I represents a rod, connecting with the hinged cover D, and with awinch, f, on one of the pintles f, to which the cap F is made fast,whereby, when said cover D is raised to permit access to the seat, thecap F will be raised and the pipe H, through the medium of the coggedsegments F F, be drawn up and caused to form connection with the neck 0of the basin 0, or with the equivalent outlet of any other fixture towhich the improvements herein described may be applied, and

when said lid is turned down the cap will be lowered and the slidingpipe passed down into the waste-pipe.

To insure accuracy and directgiess of movement, the ribs h h travel ingrooves or guides b 1) formed in the inside of pipe B; and to preventcontact of cap 0 and end of sliding pipe H, said cap is made dome-shapedor concave, as shown.

K is an arm, loosely swiveled on one of the pintles f, and formed with acam head, 7:, whereby a stem, 1, of a valve, L, in a waterpipe, L, maybe actuated to open said valve and flush the basin 0.

M is a rod, connected to the outer end of the arm K, and extendingupwardly through the seat 6?, having a knob, m, which normally rests ina recess or cup, d in said seat.

When the lid or cover 1) is raised and the seal-cap and sliding pipeelevated, leaving the way to the waste-pipe B clear, the rod M may bedrawn up, opening the valve L and flushing the basin with water; butwhen said cover 1) is down it prevents the rod M from being lifted,thereby preventing unnecessary waste of water.

N and N represent pipes, coupled at 01, and designed to carry on gasesand smells from the trap E, or which may arise through the waste-pipebelow said trap.

The operation is as follows: The cover D being down on the seat (I, theseal-joint is made, the flange of the cap F being submerged in themercury in trough B, the sliding pipe H being beneath said cap, restingin the wastepipe B and dipping into the water held in the trapE,and thewatcr-valveLclosed. 0n turning up or back the seat-cover 1) the pintlesfare revolved by reason of the connecting-rod 1, thereby throwing up thecap F, which latter, as it is raised, elevates, by means of the coggedsegments F F, the slidingpipe H until the upper flaring end, h of thelatter encircles the neck c of the basin 0, the lower end of said pipebeing then below the top of the pipe B. The way to the trap is now clearand the closet open for use.

After or during use, and while the cover D is yet raised, the basin maybe flushed or flooded by drawing up the rod M. After use the lid orcover I) is lowered, thereby turning down the seal-cap until its flangebecomes submerged in the mercury, the sliding pipe H at the same timemoving down below said cap.

The gases generated in or smells proceed in g from fecal or other matterdetained in trap will, with other gases and smells from cellartrap, passon through pipes N and N.

To prevent the mercury from being spilled by the sudden descent of thecap F, the walls of the trough B should spread as they descend, as shownin the drawings.

I have shown the seal-cap connected with the seat-cover, so as to beraised when the latter is lifted; but the connection for actuatin g saidseal-cap may be made with a hinged seat, and the joint or seal opened byone in sitting down on said seat; ora handle may be used, and theseal-cap raised bya pull or push thereon. So, too, other means oflifting the sliding pipe than the cogged segments F F may be employed.

I have shown and described mercury as the sealing medium in the trough Bbut indiarubber may be substituted therefor, the flange fin such caseindenting the rubber and forming a perfectly tight joint.

What I claim as my invention is 1. In combination with the neck 0 oroutlet of a basin, bowl, tub, or other fixture, and a waste or dischargepipe, B, a sliding pipe, H, adapted to be moved down into said wastepipeand to form a close conduit between it and said neck or outlet whenraised, substantially as shown and described.

2. The combination of waste-pipe B, having mercury-trough B, cap F, andsliding pipe H, adapted to fit in said waste-pipe when said cap islowered and sealed, and to be elevated when said cap is raised oropened, substantially as shown and described.

3. The combination, with neck or outlet 0, waste or discharge pipe B,cap F, and sliding pipe H, of intermediate mechanism, substantially asdescribed, for drawing up said pipe when said cap is lifted.

4. The combination, with cap F, of pintles f f winch f and rod I, saidcap being arranged and adapted to clear the pipe and leave itunobstructed when raised, substantially as shown and described.

5. In combination with pipe B, the mercurytrough B, having walls whichspread apart or flare as they descend, substantially as described, toprevent spilling of the mercury contained therein.

6. The cap F, having depending cogged segments F F, in combination withsliding pipe H, having ribs h h, with teeth or openings h h,substantially as shown and described.

7. The combination, with case A, of basin 0, flange-bolted thereto,waste-pipe B, and sliding pipe H, arranged and operating to form, whenraised, a connection with said basin, and a direct close conduittherefrom to said waste-pipe B, substantially as shown and described.

8. The combination of case A, waste-pipe B, having mercury-trough B,basin or receptacle (1, having outlet a, hinged cap F, having arms f f,pintlesf, and depending cogged segments F F, sliding pipe H, having ribsh h, with teeth or openings h h, and rod 1, substantially as shown anddescribed.

In testimony that I claim the foregoing I have hereunto set my hand this13th day of September, 1879.
